FEED MECHANISM FOR STONE-SAWING MACHINES.

SPBCIFECATION forming part of Letters Patent N0. 336,840, dated February 23, 1886.

Application filed October 8, 1885. Serial No. 179,335. (No model.)

be evenly distributed over a large surface, or

can be delivered to a particularportion, of the stone when such delivery is required, as in the case of irregularly shaped blocks-such as those shown in Figures 4 and 6; and to the above ends the invention consists of coneshaped spreaders arranged beneath the feed ing-tubes, and of deflecting-racks arranged beneath the spreaders, together with certain other novel constructions and combinations to be hereinafter explained, and specifically pointed out in the claims. Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Fig. 1 is a plan view of, a stone-sawing machine with my improved feeding apparatus applied thereto, a portion of the cross-beams being cut away to disclose the construction of the parts. Fig. 2 is a plan view of the coneshaped pin employed to distribute the feed. Fig. 3 is a vertical sectional view of a portion of the same, showing its arrangement in relation to the feeding-tubes. Fig. 4. is an elevation of the stone-sawing machine with my apparatus applied thereto, representing one side of the machine, a portion of the apparatus being cut away to disclose the construction. Fig. 5 is a longitudinal vertical sectional view of the machine, and Fig. 6 is an end View of the same, the saw-frame and one of the end boards of the distributing apparatus being cut away to show the arrangement of the distributing-pins and the deflectingboards.

Referring now to the general construction illustrated in the drawings, S represents the block of stone placed in position to be operated upon by the saws k k, which are mounted in the usual manner.

h h are the main frame-posts, d d girts connecting same, and h h cross-beams at the top. ff are guides fastened to the girtsd d and the cross-beams h h to form ways for the uprights e e to slidein. To the bottom of the uprights e 6 there is fastened a cross supporting-bar, 0 which carries the reservoir 0 on its upper side, and beneath which there is suspended the fixed rack a by means of the hanger-arms b b. Side boards, 12 'v, are secured to the inner faces of the arms I) b and extend down to about the level of the rack a. To the ends of these side boards there are secured cleats 1) 1), which extend downward below the boards 22 o and carry rods g g, one on either side of the machine. Two racks, trunnions or pivots o 0 which rest upon and are free to slide from end to end of the rods 99. Swinging boards as m, which extend across the machine, are supported by the pivot-points x a which rest in bearings formed in the side boards, 1; o.

The sand and water constituting the feed can be carried by means of a pipe or hose to the reservoir c,which is located at a proper height to give the necessary head to the feed as it is delivered to the distributing-pins 8, located below the delivery-tubes b,which lead from the reservoir 0. The pins .9 are used for the purpose of distributing the feed over the racks a a a for if the feed fell directly from the reservoir to the racks it would pass directly through the central stationary rack, a, and in falling to the stone S would cover but a small portion of it; audit is to obviate this difficulty that I have devised the present apparatus. The pins 3 are cone shaped at their upper points, and below the coneshaped point m there is a concave surface, m, surrounding the point, so that as the feed strikes the point an and falls into the concave cup m it will be thrown from the pin in curved lines, as indicated by the linest 10, thereby distributing the feed over a large surface. v

In order that the amount of feed thrown to one side or the other of the pins 8 may be varied, I provide each pin with a slotted lug, y, through the slot of which a bolt, y, is passed to secure the pins to the fixed rack a. By ada a are supported by.

which are justing the points of the pins to one side of the centers of the feeding-tubes b a preponderance of the feed may be thrown to one side of the pins, so that by the use of the pins alone the feed may be delivered to any particular part of the stone. v

All of the racks a a a are made of longitudinal stripst' i, which are fixed to and supported by a suitable frame-work, t" '6.

When a stone shaped as the'one illustrated in Fig. 4, with one end higher than the other, is to be operated upon, the racks a a are adjusted to throw the feed upon the higher portion of the stonesay to the points p p?--for, as represented, no sand would be required below the point 19 until the saws k k had advanced below that point. In this case the racks a. a are held in position by the pins 1 l, and as the feed is thrown or dropped upon their upper faces almost all of it will be carried forward to the lower edges of the racks, from which points it will drop upon the stone S, all spattering or scattering of the feed being pre- .1 vented by the swinging boards as m, which may 1 needed on the lower side until the saws on the be adjusted to such an angle as is necessary for the purpose named. When, as is often the case, the stone is higher on one side than the other, as shown in Fig. 6, the feed will notbe other or high side have out down some distance. In such a case as that last mentioned I employ boards n n, which are secured to bevel-faced supporting-blocks q and placed upon the rack a, to confine the feed to the portions of the stone where it is needed.

The uprights e e,which, as stated, slide in ways between the strips ff, may be connected at the top by a bar, and to this bar ropes may be attached and led to a drum shaft provided with a. cranlrhandle, by which arrangement the feeding apparatus may be raised or lowered to accommodate itself to different heights of stone.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a stone-sawing machine, the combination, with the feed-reservoir and its deliverytubes, of cone-shaped pins located opposite 3. In a stone-sawing machine, the combination, with the saw racks and saws k k, of a feeding apparatus consisting, essentially, of a feed-reservoir, c, in the bottom of which there are arranged tubes b, pins 8 8 being arranged beneath the tubes and above adjustable distributing-racks, and the cups m, said pins be ing disposed directly below the delivery-tubes and having their apices pointing upward, substantially as described.

4. In a stone-sawing machine, the combination, with a saw-rack and saws, of a feed-reservoir, 0, provided with tubes b, which pass through the bottom of the reservoir, pins .9 arranged beneath the tubes, and distributingracks a a a the racks a a bein arran ed beneath the rack a and transverse adjustable deflecting-plates x w, and the cups m, said pins being disposed directly below .the deliverytubes and having their apices .pointing upward, substantially as described.

5. In a stone-sawing machine, the combine tion, with a saw-rack and saws, of a feed-res-v ervoir, 0, provided with tubes b b, pins 8 8, arranged beneath the tubes b, a fixed rack, a, adjustable racks a a, arranged beneath the fixed rack 00, and inclined deflecting plates n n, and the cups m, said pins being disposed directly below the delivery-tubes and having their apices pointing upward, substantially as set forth.
